You all have helped me a lot so far; I am able to successfully order products on my Snipcart test account.
I’ve seen something odd happen while I’m testing, and I don’t know if the problem is from Snipcart or something generated by Sparkle and if there’s a way to work around it. When I selected the button on one page to add an item to a cart, the Snipcart overlay appeared, but the Add to Cart button from my page still showed.
And I have a button to Show the Cart on one of my pages, and it has several text elements showing over the overlay. I was looking at the items that bled through to see if they’re the top layer (or the bottom layer), but they’re actually in the middle of the layers. So I don’t know if there’s a way around this.
